cakephp displayfield混淆了吗？

Question

我正在cakephp 2.0中创建一个小应用程序

我有树模型DescCriter属于Aspects，Aspects属于Activits，Activits属于计划

我改变所有模型public $ displayField ='descripcion';

但是我想要显示与id不同的东西..在我看来我不能......

我不修复......我唯一能看到的就是id

添加型号代码

class DescCriter extends AppModel {
   public $displayField = 'Criterio'; 
    public $validate = array(
        'aspects_id' => array(
            'numeric' => array(
                'rule' => array('numeric'),
                //'message' => 'Your custom message here',
                //'allowEmpty' => false,
                //'required' => false,
                //'last' => false, // Stop validation after this rule
                //'on' => 'create', // Limit validation to 'create' or 'update' operations
            ),
        ),
    );

    public $belongsTo = array(
        'Aspects' => array(
            'className' => 'Aspects',
            'foreignKey' => 'aspects_id',
            'conditions' => '',
            'fields' => '',
            'order' => ''
        )
    );


class Aspect extends AppModel {

    public $displayField = 'descripcion';
    public $validate = array(
        'activits_id' => array(
            'numeric' => array(
                'rule' => array('numeric'),
                //'message' => 'Your custom message here',
                //'allowEmpty' => false,

                //'on' => 'create', // Limit validation to 'create' or 'update' operations
            ),
        ),
    );

    //The Associations below have been created with all possible keys, those that are not needed can be removed
